Quick Verdict
Pick Agents-A1 if you want the stronger benchmark profile. GPT-4.1 only becomes the better choice if knowledge is the priority or you need the larger 1M context window.
Agents-A1 is clearly ahead on the provisional aggregate, 63 to 58. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.
Agents-A1's sharpest advantage is in instruction following, where it averages 94.8 against 87.4. The single biggest benchmark swing on the page is IFEval, 94.8% to 87.4%. GPT-4.1 does hit back in knowledge, so the answer changes if that is the part of the workload you care about most.
Agents-A1 is the reasoning model in the pair, while GPT-4.1 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. GPT-4.1 gives you the larger context window at 1M, compared with 262K for Agents-A1.
